FW: [aspectc-user] Visual Studio and ac++ ?

[Benoit Lefevre]

Hi Matthias

	I finally found time to try ac++ with VC8.

	Your advice helped me a lot as I had the Trace example producing 
	weaved source file. 

	I didn't try to compile this file as it wasn't relying on very complex
	code.

	Instead, I directly tried to weave a very simple aspect on one of my
	project cpp file.

	That's where troubles got in (4 of them).

	I don't intend to ask you with this mail to solve them as VC8 is not 
	clearly stated as been supported, but rather help you (a little) for
	your future port of visual studio 7 Plug-in toward the VC8 version.

	All these troubles occurred at parsing step while using the -v9 option
	of ac++

	Here they are :

		1) ac++ don't seem to support that kind of include preprocessor
		command containing windows style backslash path separators :

			#include <in\here.h>
	
		But maybe it is rather due to Visual Studio supporting an out of
		C++ specification feature ?




		2) I got stuck on a strange class declaration :

		Here is a simplified extract of what is causing this trouble :

--------------------------
	template <bool _SECURE_VALIDATION>
	class _Iterator : public _Const_iterator<_SECURE_VALIDATION>
	{
		public:

		...

		typedef typename _If<_SECURE_VALIDATION,
		_Iterator<false>,
		_Unchanged_checked_iterator_base_type_tag>::_Result
		_Checked_iterator_base_type;

		friend _Iterator<false>;
		friend _Iterator<true>;

		...

	};
----------------------------

		ac++ don't like the first friend declaration.
		
		Note that, as I don't know what can cause this trouble, maybe I
		simplified too much this extract.



		3) The following extract of file crtwrn.h is not parsable for
		ac++ because of the second backslash :

------------------------------------
#define _CRTWRN_MESSAGE__NO_ITERATOR_DEBUGGING Iterator debugging not \
        supported in retail builds.\n  \
        Setting _HAS_ITERA##TOR_DEBUGGING=0	
------------------------------------



		4) The "using namespace" formulation doesn't seem to be
		supported by ac++, at least fot the following example:

-------------
#include <aFile.h>	// namespaces are declared within aFile.h
using namespace namespaceOne;

class A : public B
{
	...

	// namespaceTwo is defined within namespaceOne
	namespaceTwo::aType myVariable;

	...
}
-------------

		An error is reported on "myVariable" declaration.



	Hope it will help.

	Best regards.


Benoit Lefevre.

Hi,

it's definitely not a "piece of cake" to use ac++ directly on VC++ code, 
but it's also not a nightmare. I don't exactly know all changes between 
VC7 and VC8. But I know that at least new keywords were introduced. If 
you have access to a VS2003, then install the AspectC++ Add-In and look 
how it solves these problems (there is a configuration file with 
#defines and some required declarations in an extra header file that is 
automatically included, the Add-In log file contains the corresponding 
ac++ call).

When the next ac++ release is out (in the near future), then a new 
AspectC++ Add-In should be available (for VC7 and for VC8) too.

Best regards,
Matthias
